Steel–wood structure: the frame is fabricated by welding 40×60×1.2 mm thick square steel (with optional thicker options available at an additional cost) into C‑ or H‑sections. Rust removal and hot‑dip galvanizing ensure corrosion resistance, while the surface is finished with epoxy resin powder coating applied via electrostatic spraying. The door panels are made of 18 mm eco‑friendly E1‑grade particleboard, laminated with melamine and edge‑sealed with PVC. Handles feature concealed flat‑style pulls, available in PP or, for an extra charge, all‑aluminum alloy. The countertop is constructed from 12.7 mm double‑sided laminate or a solid phenolic resin board that offers acid‑ and alkali‑resistance as well as superior corrosion protection; its edges are reinforced to 25.4 mm (with optional ceramic or epoxy countertops available at an additional cost). DTC hinges and heavy‑duty ball‑bearing silent slides are employed. The cabinet base is supported by steel beams to bear the load and prevent deformation.
